Safari Animation Problems

Hello guys.
I have problems with Animations in Safari. I created a site on Firefox the last days. Now im back on the Mac. The same Animations don’t look alike. It’s like the layers are different.

I know this Topic was already discussed once or more often. But I haven’t found a fix yet. I think its a problem with Safari, but if that’s the case I have to delete this whole animation because of the user experience on Safari…
